WILLIAM STURGIS BIGELOW, OF BOSTON, MASSACHUSETTS.

FASTENING FOR DOORS, BLINDS, SHUTTERS, 800.

Specification of Letters Patent.

Patented May 14, 1907.

Application filed November 28, 1906- Serial No. 345.551.

To on whom it may concern:

Be it known .that I, WILLIAM STURGIs BIGELOW, of Boston, in the State ofMassachusetts, have invented a new and useful Imreference to fasteningsby which, when the door of the stateroom on a steamship is held partlyopen for ventilating purposes, the rattle of the door and fasteningsoccasioned by the movement or straining of the ship may be obviated, butit is evident that it is adapted to other uses.

Heretofore the partly open door has been held in a comparatively fixedposition by an ordinary hook having its shank linked into a screw-eyewhich is screwed into the door, while the hook proper at the other end,of the shank has engaged with a similar screw-eye screwed into thedoor-jamb. The length of the shank of the hook has determined thedistance at which the door shall be held open. This is the device whichI have improved. I have made the hook member of the device in, as itwere, a single piece of metal, or in connected pieces, comprising thehook proper, or means adaped to engage and wedge with the other memberof the fastening device, a shank, a coiled spring serving as a hinge forthe shank, and means for securing the spring to the door or door-jamb,as the case may be, the spring being arranged to allow to the shank, andso to the hook proper, or other engaging device, a movement in twodirections and in two directions only, viz: into and out of engagementand wedging with. the other member of the fastening device, which isadapted for said engagement and wedging and for rigid attachment to thedoor-jamb or door. In operation the two engaging members of thisfastening device are held wedged together by the force of the coiledspring.

The invention consists in a fastening of the character described fordoors or similar hinged devices, one member of said fastening consistingof means for rigid attachment to one member of the hinged device, aspring adapted to serve as a hinge for said member of said fastening,and a shank provided at the free end with means for engaging and wedgingunder force of said spring with the other hold a member of saidfastening which is adapted to be rigidly attached to the other member ofsaid hinged device.

In the drawings accompanying this specification and forming a partthereof are shown several forms of my improved fastening, in which onemember is secured or adapted to be secured to a stateroom door while theother member is secured or adapted to be secured .to the door-jamb; butit is obvious that these positions might be reversed.

Figures 1 and 2 represent, respectively, a side elevation and a plan ofsaid improve ment thus secured in its simplest form. Figs. 3, 4, 5, 6,and 7 are modifications.

D inthe several figures represents the stateroom door and J thedoor-jamb.

At Figs. 1 and 2 one member of the fastening, which may be termed thehandle member, consists of a single piece of stiff wire of sufficientlength to comprise a shank, A, substantially determining the distance atwhich the door shall'be held open, several turns to form a spring S ofsufficient resilienc a threaded end forming a gimlet screw to screw intothe door D, and a hook H upon the free end of the shank, to engage withthe opposite member of said fastening which consists of screw-eye Eprovided with a gimlet thread to screw into the door-jamb J. In thiscontrivance the wedging device lies in the hollow h of the hook H, theopposite arms of which, a, a, gradually approaching each other firmlyembrace both sides of the wire of the screw-eye E under the force of thespring S. The dotted shank and hook in this figure show the normalposition in which the shank and hook proper are held by the spring whennot in use.

In the modification shown at Fig. 5 the wed ing device lies in the taperhook H and sma 1 eye E as shown.

In the modification shown at Figs. 3 and 6 thehook proper and thescrew-eye of Figs. 1 and 2 change places, that is, the free end of theshank A is bent into a screw-eye E which in operation wedges under forceof the The Wedge is in the incline of the peg to the bracket. See Fig.7.

At Fig. 4 the stifl wire of the handle member is shown as made with adouble spring, S S ending in two points p p held in place in the door bybracket B secured to the door, as shown, while the catch of thefastening is in the bend at of the continuous wire, engaging and wedgingwith the pin or peg P formed as in Fig. 7 and secured to the doorj ambby screws.

Further description of the mode of operation of the invention isunnecessary.

I clai1n,

1. In a fastening device, two members each adapted for attachment to oneof two parts to be connected, and constructed to engage each other witha wedging action, one of said members formed into a spring whereby saidmember is held under pressure in engagement with the other member andmeans for connecting the spring end ol the member to a rigid support.

2. In a fastening device, two members each adapted for attachment to oneof two parts to be connected, and constructed to engage each other witha wedging action, one of said members formed into a spring where bysaid. member is held under rnessure in engagement with the other member,and means forn'ling part of the spring member tor eonnccting the springend of the member to a rigid. support.
